  • Nice question, thanks! It made me think about and better cement my understanding of transactions in SSIS, which is a good thing.

  • Good question.

  • This is reference to this Question :

    The Sequence Container contains three Execute SQL Tasks (Execute SQL Task 1, Execute SQL Task 2, and Execute SQL Task 3) connected by OnSuccess Precedence Constraints: Execute SQL Task 1 ==> Execute SQL Task 2 ==> Execute SQL Task 3. And Execute SQL Task gets failed, then the updates of Execute SQL Tasks 1 and 2 will be rolledback or committed?


    It is answered as Commited.


    How it'll be commited..? It'll be rolled back right?. If these Exectue SQL Tasks are placed directly in the Control Flow, then updates of Execute SQL Task 1 and 2 will be committed when Task3 gets failed. But All three are placed in the container. So they will work as a Unit. All the tasks in Container will be failed, When one Task gets failed inside the container. So Updates of Task1 and Task2 will be rolled back. But It is answered as Commited.

    <p>Please Explain..</p>

  • @dsvasudevan: I believe there is no explicit transaction, so the 3 tasks do not belong to the same transaction.

    On-topic: great question!

  • Good question...

    The logic can be well understood as below:

    For Parent : Transaction option = Required

    For Child : Transaction option = Supported/Not Supported
